[Omaroo (Chris Malikoff)]

Another vote for the Orion unit here - and whilst I'm sure the QHY version is just as good (and some say better due to a supposedly better quality USB cable) I've not used one.

The Orion is pure simplicity to configure and use. One USB cable from camera to laptop. An RJ-12 cable from camera to guide port. The PHD software mates very well to the guider and there is minimal setup - choose the camera from a pull-down menu and you're off. There is no rotational adjustment to make on the camera except getting it reasonably straight in the collar as PHD automagically detects camera skew and compensates for it.

Turn it on, fire up the software, focus and choose a star, wait for calibration to run - and it's guiding.

Brilliant for the money.

Then again - I get nearly the same performance from my webcam and PHD - except for the fact that you then require a GPUSB USB to ST4 adapter box and cable to connect the lappy to the guide port. The above cameras make it so much simpler.

Having a G11 I'm not sure what's involved in putting an EQ6 into its guide mode (called "Photography Mode" on a G11) but I'm sure it can't be too difficult.
